What are the reasons for the poor air quality in Shenyang, Taiyuan and Changchun?

1. radiation pollution: mainly from radioactive substances and light radiation generated by electrical appliances. If we only look at a single quantity, the pollution degree is very small. If radioactive sources are concentrated in the same room, the air quality index will drop over time, which will affect people's health.

Second, chemical pollution mainly comes from home decoration, children's toys and architectural coatings. Some pollution will increase with the increase of human activities, and it will stop when human activities stop, while some pollution will not be affected by human activities and is a source of continuous release. For example, building decoration materials are the source of continuous release, and the release speed will change with temperature. This emission source is harmful to people's health, so after decoration, people usually purify it before putting it into use.

Three, biological pollution, mainly from indoor wet places, such as wet walls, moldy carpets, corners that are easy to breed bacteria and viruses. Indoor pollution concentration is related to the volume in the space, so the distribution of this pollution in the building is not uniform, depending on the location of pollution sources and air circulation. The larger the building volume, the greater the possibility of biological pollution, and the distribution of pollutant concentration is relatively complicated.

Different pollutants release different pollutants, so multi-function air quality transmitter can be used to detect indoor pollutants. It can detect indoor air temperature, humidity, PM2.5, PM 10, TSP, atmospheric pressure, illumination, noise, odor, TVOC, CO2, formaldehyde, O3, CO, CH4, O2, SO2, NO2, H2, H2S, NH3 and other elements, which basically covers all indicators reflecting air quality. let us

The multifunctional air quality transmitter adopts imported sensors and control chips, which has electrochemistry, high resolution and stability. In the process of use, people can choose whether to output 485 or transmit 4G wireless network according to the use environment.

Model 485 can transmit 2000 meters, and the indoor environment data can be viewed through the monitoring platform.

Compared with Model 485, 4G wireless network is more convenient for transmission and connection. It can be viewed through the environmental cloud platform or monitoring platform, not only on the computer side, but also on the mobile phone side. It can also be matched with air purification equipment to directly form an online air environment comprehensive monitoring system.

In addition to the above two, you can also choose WIFI devices, and the detected data can also be viewed through the monitoring platform or the environmental cloud platform. But with this kind of WIFI transmission, networking can be realized with the help of the field network. USB driver-free configuration equipment parameters, only one USB data cable is needed on site.

Regarding the multifunctional air quality transmitter itself, you can choose wall-mounted installation or ceiling-mounted installation. ABS material, durable; Compact shape makes it need less installation environment and more applicable scenarios. Can be widely applied to smart homes, office buildings, schools and hospitals,
